Vulnerability discussion

Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. To meet password policy requirements, passwords need to be changed at specific policy-based intervals. If the network device allows the user to consecutively reuse their password when that password has exceeded its defined lifetime, the end result is a password that is not changed as per policy requirements.

Check content

From the vSphere Web Client, go to Administration >> Single Sign-On >> Configuration >> Policies >> Password Policy. View the value of the "Restrict reuse" setting. If the "Restrict reuse" policy is not set to "5" or more, this is a finding.

Fix text

From the vSphere Web Client, go to Administration >> Single Sign-On >> Configuration >> Policies >> Password Policy. Click "Edit" and enter "5" into the "Restrict reuse" setting. Click "OK".

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
